The
Gambsodule puzzleCreator/designer:
Gianni A. SarconeWith
a
simple
paper
sheet,
two
cardboard
pieces
and
a
string we
can
make
an
original
topological
puzzle:
the Gambsodule.
This
puzzle
is
composed
of
3
paper
loops
held
together by
their
edges.

Let's
Start

To
construct the puzzle take a A4 format sheet and fold
it into 3 parts, then cut out the third part along
the fold line as per diagram (fig. 2a). Once
the paper strip is cut out, make two lengthwise incisions
in it (fig. 2b & c). At the same time,
with the remainder of the paper sheet make a paper
ring of approx. 2 cm in diameter and join two 3x3
cm cardboard squares at the ends of a string 30 cm
long (fig. 1).
Then, twist the paper strip (fig. 2d) in order
to obtain the shape illustrated in fig. 2e.
Stick now the ends of the paper strip together with
Scotchtape (fig. 3a) and cut off from this part
a small piece (fig. 3b). Slip the loop of the
Gambsodule through this small "button-hole" (fig.
3c), slip the paper ring on the reversed loop (fig.
3d)...

...and place across the loop the string with the
cardboard pieces (fig. 4a). Finally, take
out the loop from the small hole (fig. 4b)
and pull back the string between the loops of
the puzzle (fig. 5a). The diagram in fig.
5b shows how the puzzle should look.
